Xalatan

Xalatan eye drops contain the active ingredient latanoprost, which is a type of medicine called a prostaglandin analogue. It is used to treat raised pressure within the eyeball.
The pressure within the eyeball is naturally maintained by a continuous flow of liquid called aqueous humour through the eyeball. Aqueous humour is produced by a part of the eye called the ciliary body. It drains out of the eyeball through channels called the trabecular meshwork. If the outflow of aqueous humour is blocked, the aqueous humour builds up inside the eye, increasing the pressure within the eyeball. This pressure needs to be reduced, as otherwise it can damage the optic nerve and impair vision as a result.
Latanoprost reduces the pressure in the eye by mimicking the action of a naturally-occuring prostaglandin. Prostaglandins are a group of natural body chemicals found in many places in the body. In the eye, they increase the drainage of the aqueous humour out of the eyeball. Latanoprost is a synthetic prostaglandin that acts on the same receptors in the eye as the natural prostaglandins. It therefore causes an increase in the drainage of aqueous humour out of the eyeball. This decreases the pressure within the eye. Latanoprost is used to lower raised pressure in the eye, for example in glaucoma.

Precautions
The medication can change the color of eyelids. Also it can change eyelashes and fine body hair and increase color, number, length, thickness of lashes or hairs.
